APPARATUS FOR WAVING HUMAN HAIR.

Application tiled June 16, A1926. Serial No. 116,4411;`

' comfort of the person whose hair is being operated on` and to greatly simplify the apparatus, and thus reduce the cost of manufacture thereof, and diminish the liability of derangement, which results'in temporary loss-of use of the apparatus and expense byl My invention consists in way of repair. whatever is described by or is included within the terms or scope of the appended claims. In the drawings:

Fig. 1 is a view partly in side elevation and partly in perspective of enough of the apparatus to illustrate an embodiment of my invention;

- Fig. 2 is a view in vertical section of the heating apparatus;

Fig. 3 is a detail view in perspective of the hair clamp. g

By way of premise, it is desirable to say that the embodiment of my apparatus in its preferred form is the usual or ordinary one of fa group or collection of electric heatersV sufficient in number to treat a whole head of hair at one time, each heater operating, as is usual, upon a single strand of hair, and the collection of heaters being suspended from an overhead support or chandelier, or canopy. Each heater, as is common, comprises a structure within which is contained the twisted or curled strand of hair to be treated, moisture being provided for the generation of steambut experience has shown that it is objectionable to use a closed chamber 'within the heater for the hair bea moisture absorbing protecting device is.

used to catch steam passing from the end next the scalp, so asato prevent contact of steam with the scalp to the discomfort and possible injury of the scalp.

Myheater comprises two concentric tubes of substantially the same length, an outer one, 10, which constitutes the external casing, and an inner one, 11, which provides the central space or steaming chamber in which the hair wound or twisted upon a central rod, 12, as usual is placed. The tubes, 10 and 11, are of metal, preferablyaluminum` and the inner tube, 11, has applied to its exterior, the electrical heating devices,

as usual, to which current is supplied by flexible wires, 13, which at one end have a plug for detachable connection with a socket attached to and depending .from an overhead canopy, the wires, 13, being, of course, of a length to reach to the head of the subject seated as usual in a chair.

It` of course, is understood that the tubular lbody formed by the concentric tubes, 10 and A11,`must be separated from the curling rod, 12, until the hair has been wrapped or twisted upon said rod, and the customary solution containing flannelwrapped around the hair, and then the heater is placed endwise over .the` rod, and hair, and solution containing strips wrapped thereon, and the partsjflocked together in this assembly for thefperiod required for the heating operation. At the bottom of the rod or the part next the scalp, aV device is used toengage the strand of hair as close to the scalp as possible (sometimes a String is used to tie the strand to the rod),'and when this device is of metal, it is important to prevent direct contact thereof with the scalp to avoid injury or discomfort from heat, and it is also necessary to protect the scalp from escaping team, this `being usually done by a'disc of e t, v

My hair enga ing device comprises a platewhich may e of disc form composed of two members, 144 and 15, respectively, which lare secured together at the center by a stud, 16, which projects above the upper member, and is screw-threaded for a purpose explained hereinafter, the disc being provided with a radial slot, 17, which exten dsto the rim, and also comprises the slidable clam ing. device, 18, slidably connected with the isc and which 4at one end is formed into a hook, 19, which may be moved to and ufrom the radial slot inthe-disc either to 'the slidable clamping device to clamp a strand of hair at the inner end of the slot preliminary to twisting the hair on the center rod or to release the strand of hair when the treating operation is over. I make the disc of the two members as a convenient way of slidably connecting the clamping device therewith, the shank of such device being placed between the two members, one or both of which is provided with a straight groove to contain and to guide the shank otfthe clamping device. The end of the clamping device opposite the hook projects sutlicientl far from the disc to enable it to be `readily caught hold of by the fingers for manipulating it. When the strand of hair isgripped between the inner end of the radial slot and the clamping device, by the screwing of the center rod, 12, upon the threaded art of the stud, 16, a clamping grip will be exerted upon revent its accidental movement during the urther use of the heater. There is no turning movement of the two members of the disc with reference to one another, and as stated, the two members are used simply as a convenient way of connectin therewith the slidable clamping device. ecured to the side of the disc which comes next to the scalp in use is a disc, 20, of felt for the purpose of absorbing escaping steam so as to prevent hurt or injury to the scalp from steam. Said felt5 disc has a radial slit that aligns with the radial slot in the disc members, 14 and 15, for the passage of the strand of hair into said radial slot.

A very important advantage of my hair engaging device due to the slidable hair clamp, is that there is no danger whatever of hair being cut as exists in the case of the well known rotary disc type of hair engaging device, especially when pliers are used with such a device, the rotating discs in ejiect being blades of a pair of shears. Y The inner and outer tubes, 10 and 11, are secured together at the bottom b an interposed ring, 21, and this ring an the adjacent ends of the tubes rest in contact with the upper metal disc 14, when the heater is in operative position, and the locking together of the heater and the curlin rod, and thus the entire assembly is e'ecte by the very simple device of a knob, 22, having a projection or the upper end of the 'ro which when the heater is slipped over the rod pass through a diametrical slot, 24, in the top of the outer tube, 10, and by Aa partial rotation of the .heater with the knob, 22, and lugs, 23,

above suoli top the lugs and radial slot are turned out of alignment and the lugs en age a solid portion of the outer tube top. gU locking is secured by a reverse operation. It will be seen that the act of turnin the lock ing lugs out of alignment with t eslot in (projections, 23, at 1 the top leaves the slot ends open, and thus provides that open condition of the heater which is necessary to allow theeseape of steam 'at the top, and thus diminishes the likelihood of excessive discharge of the steam at the bottom and next the scalp of the individual. v

The knob, 22, besides its rotary movement on the rod has an axial movement to enable it to be pulled upward to pass the radial lugs, 23, through the slot, 24, and it is so pulled against .the pressure of a coil spring, 25, interposed between the shoulder on the rod` and the end of a chamber in the knob. The pressure of the spring tends to move the knob and its projections against the top of the outer tube with sufficient force to securely hold the parts together. When the k'nob, 22, :is turned to place the lugs, 23, in alignment with the diametrical slot, 24,'the spring automaticallypushes the projections through the slot and thus automatically releases the locking connection so that the operation of removing the heater from the head is quickly and easily accomplished and without any discomfort to the subject whose hair is being treated. Inasmuch as the knob, 22, is pulled outward for the locking operation, it will be seen that the comfort of the person being treated is romoted as there is no thrusting or pus ing motion against her head.
